Abstract (en)
[origin: EP1845645A1] A base station apparatus (100) has an FFT unit (102) which FFT transforms a base station GI deleted signal (S BGID ) obtained by removing a guard interval from a received signal and outputs a base station FFT signal (S BFF7 ). A mobile station separating unit (103) separates the base station FTT signal (S BFFT ) in correspondence with mobile stations, based on a frequency channel signal (S BCH ) provided by a frequency channel signal generator (105) and indicating a correspondence relationship between identification numbers assigned to mobile stations and frequency channels. Delay profile estimation circuits (104-1) to (1 04-M) corresponding to the mobile stations each estimate a delay profile from the input mobile station separated signal (S BDMX ) and output delay profile estimation signals (SBDP(1)) to (SBDP (M)). The base station apparatus (100) thus estimates delay profiles independently for signals transmitted by a plurality of mobile stations and contained in the received signals received in one OFDM symbol time.
